    I have the same situation as the author. The 3C0907801B C2.1 Hw013 Sw0001 driver spits error 02435 - Supply Voltage for Control Module for Right Channel. Replaced motor, power supplied from the battery directly to the contacts of the controller plug to the pins of the motors - they work. Spells with epb switch sequences cleared, and nothing works only on one wheel. During the test, the motors are actuated and on the left one you can hear how the drive works and you can hear the chirping of relays in the controller, on the right one there is silence. Apparently drivers with the letter B have a problem with the software, and the question here is whether I can insert with a different letter. According to http://nateronline.com/Technical_Bulletins/2007.05.15_update_program_Elc_park_brake.pdf
    need to be changed to the letter G, but I don't see such a stimulant

    The voltage was applied to the driver plug when it was unplugged, I did not stab the cables with the needle. So it was safe for the helm.

    Someone has been struggling with this lately. The current consumption by the motor was important.

    The topic is mastered. It turns out that each engine has two fuses, in my case the aluminum oxidized at the tip of the fuse. The mistake I made was that I looked at the fuses with the flashlight and they looked healthy, and the second error was that I checked the voltage on the controller plug with a voltmeter and the voltage showed on it. I did my own work inadvertently.
    Aaaa, sometimes someone is looking for ABS coding here, I had: 3c0698109a - 13569 coding. Thanks for your commitment.

    Hello
    a few months ago he refused to give me a manual from the driver's side
    The motor has been replaced, unfortunately, there is a lit icon on the meter and the sound when it is lowered
    vscan does not detect any errors and the manual on both wheels is working properly
    Anyone have any idea why this icon is lit ???

    Of course, it's deleted, that's why there aren't any.

    Hello
    The same problem for me, I do not even try to move the left clamp, the bulb does not light either. Has anyone checked with a meter whether there is voltage? For me, it shows a short circuit all the time - can it be the fault of the driver?

    You have 2 fuses separately in the right box

    hehe :) fun fact
    Today, after driving about 30 km, it stopped squeaking and the manual one repaired itself :) You can see the driver must catch some error that can not be deleted even by disconnecting the battery. Out of curiosity, I will check by disconnecting the plug if the short circuit still shows, so far I am glad that it does not torture me with this squeal anymore

    Hello, I had the same problem, so I replaced the brake calipers, I replaced the button from the manual, I packed the errors, make the adaptations of the calipers and the manual began to work normally

Topic summary

The discussion revolves around a parking brake failure in a VW Passat B6 (3C) after the replacement of front and rear brake discs and pads. The user encountered issues with the parking brake system, particularly with the right rear caliper, which showed a lack of power error. Attempts to reset the system using VCDS and disconnecting the battery were unsuccessful. Various troubleshooting steps were suggested, including checking wiring continuity, cleaning contacts, and testing the brake controller. The user eventually replaced the brake controller, which resolved the issue, but they sought assistance with coding the new controller. The conversation highlighted the importance of proper voltage supply and the potential for issues arising from incorrect installation or component failure.
